In general a combination of ublox M8N + HMC5883/5983 chipset can work with Mindracer. Can be from any vendor as long as manufacturing quality is fair.
You can have a check on this one from HobbyKing. It looks compatible with 30.5 X 30.5 standard mounting hole (need to remove the case), that can be stacked.
Or you can check out this one here. This one looks come with the right JST-GH connector.
As all using same chipset, so will perform no big difference. The hobbyking one still using DF13 connector, so you may need to do some wiring job to connect to MindRacer.
Please note that i tried neither models, so just for your reference.
